The field for the O2 finale is made up of the top eight players in the world rankings, meaning the stars of the menâs game spend the year earning ranking points, with the ultimate prize a trip to London in November.

Djokovic ensured he will be back in the capital thanks to a blistering start to the year which saw him win his first 41 matches, and book his Finals place by the middle of May.

And Nadal, runner-up to Roger Federer last year, made sure he would join the Serb in the London field with his second-round win over Matthew Ebden at Queenâs Club last month.

âItâs always a pleasure to play in London,â said the Spaniard. âItâs a fantastic city and the O2 is one of the nicest indoor stadiums in the world.

âIt was a fantastic tournament last year for me, playing in the final, with very emotional matches.

âIâm very happy to be qualified and to come back again this year.â

More than 250,000 fans have come to the O2 in both the last two years, and among them have been a few familiar faces.

Diego Maradona attended almost every session of last Novemberâs event, while Kylie Minogue and Michael McIntyre have also been in the stands.
